Long range acoustic transmission loss measurements were made in the marginal ice zone of the northern Denmark Strait area using two aircraft. One aircraft flew prearranged tracks, dropping standard U. S. Navy explosive charges, while the second aircraft remained in the area of deployed calibrated sonobuoys, acting as a receiving platform. Received signals were recorded broadband aboard the monitoring aircraft. These broadband recordings were analyzed by filtering, squaring and integrating to obtain energy density in selected 1/3 octave bands. (Author)
